Littelfuse SMBJ18A is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode designed for protection against transient voltage spikes in electronic circuits. With a peak pulse power dissipation of 600 watts and housed in a compact DO-214 package, this surface mount device is ideal for use in industrial, automotive, telecommunications, and consumer electronics applications.
Featuring a single diode configuration, the SMBJ18A provides reliable clamping of transient voltage surges with a minimum breakdown voltage of 20 volts and a maximum reverse stand-off voltage of 18 volts. The clamping voltage is tightly controlled at 29.2 volts, ensuring devices downstream are safeguarded from damaging voltage spikes.
This diode supports a wide operating temperature range of -65°C to 150°C allowing it to function in harsh environments. The maximum peak pulse current rating of 20.6 amps ensures robust surge absorption capability. Additionally, it features low reverse leakage current and electrostatic discharge (ESD) protection suitable for sensitive electronics.
The compact physical dimensions (4.57mm length, 3.94mm width, 2.237mm height) enable efficient PCB layout in automated manufacturing. The 2-pin configuration simplifies installation and connectivity in transient voltage suppression circuits.
This Littelfuse TVS diode is an essential component in protecting electronic devices and systems from transient voltage damage in industrial, laboratory, manufacturing, automotive, and telecommunications sectors.
